Use integer literals and avoid coercions where needed

[IndrajeetPatil]

• Use integer literals and avoid coercions where needed
• Following our coding standards

As mentioned here:

### Control Flow

* Conditional statements should always evaluate to `TRUE` or `FALSE`, i.e. we 
  don't encourage `if (length(x))` but rather `if (length(x) > 0L)`.
* We avoid loops whenever possible and use functions like `purrr::map()` and 
  friends when possible and prefer them over R base counterparts like 
  `base::lapply()`.

Wow thanks @IndrajeetPatil for that hard work. Will review in detail later

This is how benchmark results would change (along with a 95% confidence interval in relative change) if f8644ab is merged into main:

•   :ballot_box_with_check:cache_applying: 26.8ms -> 26.9ms [-1.74%, +2.82%]
•   :ballot_box_with_check:cache_recording: 1.3s -> 1.3s [-1.06%, +1.46%]
• ❗🐌without_cache: 3.4s -> 3.47s [+0.03%, +3.82%]

Further explanation regarding interpretation and methodology can be found in the documentation.
